Examples of java.io.DataOutput.writeInt()

java.io.DataOutput.writeInt()
Writes an int value, which is comprised of four bytes, to the output stream. The byte values to be written, in the order shown, are:
```
 (byte)(0xff & (v >> 24)) (byte)(0xff & (v >> 16)) (byte)(0xff & (v >>    8)) (byte)(0xff & v) 
```
The bytes written by this method may be read by the readInt method of interface DataInput , which will then return an int equal to v. @param v the int value to be written. @throws IOException if an I/O error occurs.
